The Versalign™…Not just another Chiropractic Technique System!

The trend toward Instrument-based adjusting continues to grow within the Chiropractic Profession, to the point where it is now one of the most commonly used technique approaches in today’s practice, second only to Diversified-type manual spinal manipulation.

Unique to chiropractic treatment and technique approaches, Versalign SIGMA Instrument Methods™ makes use of an advanced technical instrument for both spinal analysis and spinal adjustment. The system is driven by a sophisticated software package, designed to help Dr. Tom locate and treat spinal and non-spinal segmental dysfunction and/or fixations.

Combining Tradition & Cutting-Edge Technology…

Versalign™ does not base its approach on any specific static listing formula, leg-length analysis or chiropractic philosophy, but instead uses a straightforward neuro-functional approach based on best available evidence in the fields of neurophysiology and chiropractic science. For this reason, Versalign™ approach is easily understood and readily accepted by chiropractors, patients and medical professionals alike, around the world. Versalign™ provides a precise, gentle and preferred advanced, computer-assisted instrument-based assessment and treatment approach unprecedented in the Chiropractic profession. The key to the therapeutic response is the precise, quantified, and reproducible low force, resonant percussive impulses that are delivered to the tissue by the treatment head. The Versalign™  can be used for both spinal adjustment, non-spinal extremity treatments, and trigger point therapy. Moreover it is completely adaptable, and can be integrated easily with most existing chiropractic technique approaches, philosophies and treatment styles.

Once treated with the Versalign™ many patients request to only have this method of adjusting used and will never be satisfied with any other approach…

The Analysis function of The Versalign™ Adjusting System isolates and identifies vertebral segments that have a resistance and frequency response that is different from the expected norm for similar vertebral segments in a similar individual. Each region of the spine (cervical, thoracic, lumbosacral) is analyzed separately and the results are displayed graphically. After the analytical phase, Dr. Tom selects the segment or segments for adjustment and the Versalign™ will apply low-force, resonance percussive impulses to the selected spinal segments. The pre-test analysis of the motor unit allows the software to calculate the correct adjustment frequency based on the natural sub-harmonic feedback from pre-test analysis of the motor unit in question. The software automatically stops delivering the percussive impulses when tissue compliance has responded according to the parameters you set. The spinal region is then immediately rescanned to determine the response of the patient to treatment. If indicated the area can be re-treated and re-scanned as needed. 



Don’t Make the Mistake of Thinking all Chiropractic Mechanical Instruments are the same…

Unlike all other instrument-based Chiropractic techniques that limit their instruments to a single impulse, poorly controlled vibration, hard to understand rationale or arbitrary frequency limitations, the Versalign™ gives you complete choice in the computer-controlled therapeutic settings that work best for your patient. Better yet, the piezoelectric sensor is capable of matching the exact sub-harmonic resonant percussion force to the natural frequency of the tissue level being treated. No other treatment instrument can even come close to that claim.

Unique to all instruments on the market, the Versalign™ can also predictably and reliably deliver corrective adjustive forces across the complete spectrum from single impulse to oscillating percussion at a frequency of 12 percussions per second. The precise magnitude of the calibrated adjustive force delivered can be computer-controlled precisely within a range of 10 to 35 pound per square inch.

Standardized Condition-Based Protocols

Versalign™ also provides non-spinal extremity treatment protocols and dynamic spinal mobilization techniques and other many adjunctive procedures. The Versalign™ has a comprehensive library of built in condition-based protocols pre-programmed into software, to aid in the reduction of local muscle spasm, treatment of local trigger points, increase range of movement and to adjust extremities.

The Versalign™ is a fantastic adjusting tool for pediatric and geriatric patients who may feel reluctant to have their spinal segments manipulated by hand.

What is the basis of the Versalign™?

The Versalign™ is a computer-based, piezoelectric instrument that utilize an accelerated mass in the head of the instrument to gently percuss the tissue area being tested, giving the practitioner vital information about the motion dynamics and resonant frequency of the joint or tissue. The Versalign™  measures the stiffness of the tissue or joint by applying a light mechanical force in the form of an instantaneous shock wave and oscillating frequency; a signal is then reflected back to the piezoelectric sensor, which measures these reflective statistics, sending it to the computer for interpretation, all before the muscle can respond. The process occurs so fast that it reduces the normal defense mechanism or guarding response, caused by typical palpation.

The Versalign™ uses the same sensing technology that the aviation industry and engineers have used in order to test metal fatigue in aircraft and bridge spans. Dr. Lawrence uses this highly sophisticated technology to analyze joints and tissue with increased precision and confidence.

With this technology, musculoskeletal conditions can be managed by increasing range of motion, eliminating fixation and improving functional capacity of patients through specific manipulative techniques assisted by the instrument in a precise and reproducible manner. The Versalign™ enables the practitioner to analyze using a sophisticated instrument, treat the dysfunctional area and then reanalyze. This provides pre and post data which is very beneficial while overseeing the patient’s course of care. It provides a method to track treatment progression that is precise, gentle and preferred.

How can the Versalign™ be so gentle?

The Versalign SIGMA Instrument virtually puts all the fears of manual treatment to rest. The Versalign SIGMA Instrument utilizes a precise oscillating force with uninterrupted motion. It is able to increase mobility of the spinal segments by reducing or eliminating the fixations. It uses soft tips that are comfortable to the human body to exert a tapping force that “unsticks” the joint.

Precise and Preferred

Versalign 5


1). Soft Tissue conditions such as trigger points respond well to the percussion forces of the Versalign™ . The forces are delivered in a sub-harmonic, metered, precise nature to create oscillation and enhance range of motion.

2). Neurologically, the Versalign™ takes advantage of the interplay of the type I, II, and III mechanoreceptors with the type IV nociceptors creating an inhibition of pain, increasing neuroactivity and restoration of normal nervous system tone.

3). The Versalign™ is very comfortable for patients of all ages due to the fact that there is no application of manual rotation or thrusting forces.

4). The patient is treated in a comfortable way without the need to turn or hyperextend parts of the body, head or neck. Thus this greatly reduces any issues associated with osteoporosis, vertebral artery conditions or other concerns that more aggressive techniques might not address.

XPRESSCHIRO is proud to be one of the few providers in the Pittsburgh area to offer the Versalign™!

    Advances in computers and engineering technologies have been able to uniquely blend with Chiropractic in order to both analyze and treat the human body in such a way that was never before realized. The potential for the human being to end pain and to achieve their peak nervous system function has never been greater. Humans are consistently asking their bodies to perform at higher levels. Now we have the techniques and the technology to match the demand placed on the spine and the nervous system. We now have the capability to fine tune our own energy and enhance every aspect of our lives.

Complex Technology, Simple Solution. The Versalign™.

    You can achieve maximum structural health for your body now and in the future beginning with a simple anatomical concept. The nervous system (the brain and all the nerves) controls every function of your body. If this network is interfered with, pain ensues, as does bodily malfunction, resulting in sickness and diminished overall health. The “something” you can do to improve performance and contribute towards maximizing your health is to maximize the health of your nervous system. There are several ways to do this. The number one way is allowing a Dr. Tom using the Versalign equipment to analyze and treat your nervous system.

How does the Versalign work?

    To better understand, let’s examine the idea of palpation. When a Chiropractor palpates your spine, they are checking for joint motion and whether there is acceptable fluidity or abnormal rigidity. Improper spinal joint motion affecting your nerve function and transmission of communication to organs and cells is called a subluxation. In a similar fashion to palpation, the Versalign can determine whether the vertebra’s motion is too rigid or too fluid. The spine should not be too rigid (hypo-mobile). However, instead of utilizing the doctor’s judgment as to what areas are hyper-mobile or hypo-mobile, the Versalign measures precise levels of motion with technology used in the aviation industry that detects airplane metal weaknesses. Therefore, the Versalign can isolate a problem area faster and more accurately than manual procedures.

The Versalign

Combines Tradition with Technology

The piezoelectric sensor in the Versalign instrument responds and registers information faster than your body’s ability to react. Therefore, a precise and accurate picture of the extent of rigidity or fluidity of each vertebra is reflected.

A light force is introduced into the vertebra to check motion, it is reflected back to the piezoelectric sensor, which measures the reflective force, sending it to the computer for interpretation, all before the muscle can respond in its normal way. Isn’t that incredible? This is the same technology and same type of instrument that NASA engineers have used in the space program in order to evaluate the integrity of the ceramic cooling tiles on the outside of the space shuttle. The aviation industry, as well as civil engineers have used this technology in order to test metal fatigue in aircraft and bridge spans.

Chiropractors are now able to use this highly sophisticated technology applied to the human body in order to determine proper function. We can have the same level of care given to our bodies as multi- million dollar spacecraft. Doesn’t that give you a sense of being special and give you a higher level of confidence?

How can anything so gentle and comfortable change my spine?

    The Versalign utilizes a precise oscillating force with uninterrupted motion. It is able to increase the mobility of the spinal segments by reducing or enabling motion in the abnormal areas. In other words, the Versalign is “unsticking” the joint. Have you ever seen a woodpecker tapping in an oscillating fashion on a tree? It is hard to believe, but you can watch them bore right through the hardest wood! The Versalign taps in much the same way but uses soft tips that are comfortable to the human body and do not create damage.

Versalign™ Delivers Results



    First, Dr. Tom will engage in a one-on-one conversation with you to determine your medical history and the possible causes of your problem. The adjustment and treatment procedures then can be customized to fit each patient’s needs.The next step in evaluation and treatment is to utilize the Versalign’s sophisticated computerized analysis to pinpoint the problem areas. The information is then charted graphically on a computer monitor, so your doctor can detect the problem areas on each and every visit

Your doctor will now begin treatment with the Versalign. By applying The Versalign’s resonant force impulses precisely to the affected areas, you will receive gentle, effective treatment to that specific area, thereby reducing the subluxation. This will relieve the pressure on the nerve, allow the nerve to heal and restore the nerve’s ability to transmit signals to and from the brain more freely. Most importantly, it will help relieve the pain! In addition, your doctor may again take the readings after the adjustment with the Versalign to compare the results. That’s putting analysis on a whole new level!

  If you are looking to enjoy more quality time with your family, have more energy and less fatigue, perform better at work and live life to the fullest with less limitations, then give Chiropractic and the Versalign a try! You’ll be very glad you did!
